We mainly do new and add-on systems a few retrofits no grids no high piled storage no extra hazard. Usually all light and ordinary hazard.

How do most of you guys size your pipe other than using a hydraulic calculation program? I have been using a pressure drop chart that list pressure drop and velocity in schedule 40 pipe for water at 60°F per 100 feet drop. So far this has worked for me but now I have someone questioning my method. Should I be going back to the pipe schedule method?
